Send both selectedText & Value to requestItems event

Hi all,
Please advise.
After selected 1stCombo, then bind 2ndCombo base on 1stCombo selected value & text.
Thant's why I need to send both selectedText & Value from ClientScript at ClientSelectedIndexChange.

My code is as below

<telerik:RadComboBox ID="Cbo1" runat="server"

CssClass="label" Label="Combox1 :" Skin="WebBlue"

OnClientSelectedIndexChanging="LoadCbo2l"

OnItemsRequested="Cbo1_ItemsRequested"

onclientitemsrequested="ItemsLoaded" ViewStateMode="Enabled"

></telerik:RadComboBox>

<telerik:RadComboBox ID="Cbo2" Runat="server" CssClass="label" Label= "Combox2 :"

Skin="WebBlue" OnItemsRequested="Cbo2_ItemsRequested"

OnClientItemsRequested="ItemsLoaded" ViewStateMode="Enabled">

</telerik:RadComboBox>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function LoadCbo2(combo, eventArqs) {

var 2ndCombo;

var item = eventArqs.get_item();

2ndCombo.set_text("Loading...");

if (item.get_index() > 0) {

Cbo2.requestItems(item.get_value(), false);

}

else {

2ndCombo.set_text(" ");

2ndCombo.clearItems();

}

</script>

</telerik:RadCodeBlock>

With this I only get selected value at Cbo2_ItemsRequested event, when I try to get with Cbo1.SelectedItem.Text directly, the text I selected is not yet there.
How can I get both, please?

Thanks and best regards

Can't find ASP.NET Checkbox in Radgrid row with Client side Javascript

I can't find ASP.NET Checkbox in Radgrid row with Client side Javascript in the RowDatabound event. I would think this would be simple to do. I must be doing something silly.

I am able to find a Telerik control but not a ASP.NET control

function RadGrid1_RowDataBound(sender, args) {

// this works

var radTextBox1 = args.get_item().findControl("LastName"); // find control

radTextBox1.set_value(args.get_dataItem()["Enabled2"]);

// This does not work

var MyCheckbox = args.get_item().findControl("CheckBoxEnabled"); // find control

}

Here is the grid code

<telerik:GridTemplateColumn HeaderText="Enabled" AllowFiltering="False">

<HeaderStyle Width="40px" />

<ItemStyle Width="40px" />

<ItemTemplate>

<telerik:RadTextBox ID="LastName" runat="server" Width="80px" />

<asp:CheckBox ID="CheckBoxEnabled" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

Thanks

Contextmenu on a custom command.

Hi.

Is there a way to make a custom command show a context menu?
Just as if the command icon was the root level of a dropdown menu.

Thank you

Remove Column error - Index was out of range.

Telerik.Web.UI : runtime = v2.0.50727, ver = 2008.2.723.20

Error when removing column from grid.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Process I am going through:

1. user selects add column on the page
2. Post back, add column to datasource
3. rebind grid
(grab data from datasource, clear columns from grid, add all current columns)
4. user selects delete column
5. confirm delete
6. postback, delete column from datasource
7. rebind grid
(grab data from datasource, clear columns from grid, add all current columns)

This works if all of this is done continuously. However, if I navigate off of this page at before step 4 and return to the page and continue, then I receive the error above.

Note: on NeedDataSource event I am setting datagrid.DataSource to the System.Data.DataTable

i dont know if it has to do with the viewstate? i tried to provide as much info as i can, let me know if anything else is required.

$find doesn't find

Hello everybody.
I can't succed in find anything with $find('objectID') method.
I'm using a webapp structure consisting of one page that loads dynamically a couple of UserControls implementing various functions.
On the other hand document.getElementById('objectID') give me back the object, so I'm pretty sure the objectID is correct.
Any idea?

Thanks in advance

Andrea

Selected Items Empty After Upgrade

Hi, I just upgraded my controls in my working DNN 5.6 project from 2010.3.1215.35 to 2010.3.1317.35. After the upgrade the SelectedItems collection is always empty. I have a grid control and respond to NeedDataSource. The data displays properly and I can select a few rows after which I enter a button event handler where I retrieve the selected items. Inspection of the control shows the data source is null, however, a 2nd request for data is never issued by the control. After doing nothing in the button's event handler the page is displayed with the original data.

Telerik.Web.UI is not in the GAC

The proper dll version is in the DNN\bin folder

I cleared all Telerik.Web.UI dlls from C:\Windows\Microsoft.NET

I have a updated the binding redirect:
<bindingRedirect oldVersion="2010.2.929.35" newVersion="2010.3.1317.35" xmlns="urn:schemas-microsoft-com:asm.v1" />

This was working perfectly before the upgrade. Any ideas as to what happened and how to fix it?

Web.config Multiplicity

I'm running Dot Net Nuke 5.6, VS 2010 and Telerik 2010.3 and have a catch 22. It seems that I have multiple web.config files and maybe some conflicts.

I have the Telerik tag defined in my web.config located in the virtual directory of my site.

To use a Telerik control on my page in the VS 2010 designer I need to have a web.config file local to the project that defines the Telerik tag:

<pages>

Without it I get the error:

Error Creating Control - radGridCustomerPoolThis control cannot be displayed because its TagPrefix is not registered in this Web Form.

However, with a local web.config in the project folder I get the following error on my page in a browser outside the VS environment.

DotNetNuke.Services.Exceptions.ModuleLoadException: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Why isn't VS picking up the tag definition in the virtual directory?

Any ideas?

ReadFile Error

I am trying to set the content and I am getting a ReadFile error. BC30451: 'ReadFile' is not declared. It may be inaccessible due to its protection level.
On a different page, the code works. But whenever I create a new page, it will not allow me to enter the code. I dont know what is going on.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not Page.IsPostBack Then

Dim temp As String = Request.QueryString("temp")

Dim path As String = Server.MapPath("~") & "/Admin/Templates/Template" & temp & ".htm"

RadEditor1.Content = ReadFile(path)

End If

End Sub

Please help.
